S2Disking in another possible mechanical treatment, and it has the merit of not disturbing the natural drainage. However, up to the middle 1950s, disking had not been tried on the Eastern Shore. Since disking seemed to offer advantages over bulldozing, a study was started in 1956 to determine its effectiveness. Some of the questions we hoped to answer were: How intensively should an area be treated? What species and stem sizes of hardwood trees and shrubs are eliminated? Which ones are only set back and soon recover? How fast do these recover? (i.e. how long after treatment can pine seedlings start and still become dominant?) This report describes what we learned about these questions and about the role of disking in Eastern Shore timber management.S3.

Because of the growing need for wood fiber in the pulp and paper industry there is an opportunity for sawmill operators to increase their income by converting hardwwood sawmill residues (slabs, edgings, and trim) to pulp chips. By selling wood chips and reducing residue-disposal costs, sawmills could improve their utilization of sawlogs. But to justify the installation of debarking and chipping machines, and to know what such machines could contribute to his business, the sawmill owner must have a thorough understanding of the costs involved in chip production. To help him in this we have made case studies of seven sawmills in southeastern Ohio, eastern Kentucky, and Tennessee, and have analyzed all the factos of cost involved in chip production.
